What a neat ring! Most definitely handmade and most likely a one-of-a-kind. The seven cameos are all carved shell and are set in 14k yellow gold with cannetille style details. The ring is currently a size 6 but we could have it adjusted up or down upon request. The dimension of the ring top is 1" left to right and 1 1/4" top to bottom. Each little cameo is approximately 3/8" by 7/16".
